The present invention is directed to a liquid transfer material formed from a necked laminate and a process for making the laminate. The necked laminate is formed from sheet layers of at least one non-elastic neckable material laminated to at least the film non-elastic film defining a longitudinal and transverse dimension. At least the film layer of the laminate is apertured in an area where liquid transfer through the laminate is desired. The entire laminate may also be apertured. The non-apertured part of the laminate remains extensible and retractable in at least one dimension without significantly reducing the breathability and/or liquid barrier properties of the film layer. This laminate extensibility and retractability is the result of striated rugosities in, for instance, the longitudinal dimension of the film layer which enables the necked laminate to have an amount of extensibility and retractability in the transverse dimension. A breathable laminate may be made by first partially stretching the non-elastic film layer, attaching a non-elastic neckable layer to form a laminate and then stretching the laminate to neck the laminate and lengthen the film to its desired fully stretched configuration.

The present invention is directed to a composite material and a process for making the material. The composite material may be breathable and is formed from at least one layer of an elastic material and a necked laminate of sheet layers. The sheet layers include at least one non-elastic neckable material laminated to at least one non-elastic film defining a longitudinal and transverse dimension wherein the laminate is extensible and retractable in at least one dimension without significantly reducing the breathability and/or liquid barrier properties of the film layer. This laminate extensibility and retractability is the result of striated rugosities in, for instance, the longitudinal dimension of the film layer which enables the necked laminate to have an amount of extensibility and retractability in the transverse dimension. A breathable laminate may be made by first partially stretching a filled non-elastic film layer, attaching a non-elastic neckable layer to form a laminate and then stretching the laminate to neck the laminate and lengthen the film to its desired fully stretched configuration. Attachment of at least one layer of an elastic material to the necked laminate further provides stretch and recovery in at least one dimension.

A breathable, substantially liquid impermeable laminate is provided that is permanently conformable to the contours of a wearers body when used in a personal care absorbent article or a medical article. The laminate includes a breathable (preferably microporous) film and a fibrous nonwoven web. Both the film and the web are extendible in a cross direction to a width at least 25% greater than an original, unstretched width upon application of a stretching force. The web and the film, and the overall laminate, exhibit little or no retractive force once they have been stretched. A diaper or other garment can be constructed in undersized fashion using the laminate, permitting material savings. When the garment is worn, the laminate stretches only where needed to provide a substantially perfect fit on the wearer. The minimal retractive force avoids the skin marks, rashes, etc. that can result from elastic garments.

A breathable, substantially liquid impermeable film and laminate are provided for use in a wide variety of personal care garments and protective garments. The film, and laminate containing the film, are extendible in a cross-direction to a stretched width which is at least 25% greater than an original, unstretched width. The film and laminate have a first water vapor transmission rate of at least about 500 grams/m -24 hours coinciding with the unstretched width. The film and laminate have a much higher second water vapor transmission rate which is at least about 225% of the first water vapor transmission rate, and not less than about 4000 grams/m -24 hours, coinciding with a stretched width that is only 25% greater than the stretched width.

The present invention provides a one or two step method for bonding and creping or double creping a nonwoven web. In the method of the present invention, a nonwoven web is adhered to a creping roll and bonded while on the creping roll. The bonding of the nonwoven adheres the nonwoven to the creping roll in a pattern of the bonding roll. Once creped from the creping roll, the resulting nonwoven web is creped in the pattern of the bonding roll. The creped nonwoven webs of the present invention are useful in a wide variety of application including as wipes, liners, transfer or surge layers, outercovers, other fluid handling materials and looped fastener materials.
